Question

STATEMENTA:
if speed of a particle is zero at an instant then average speed for the interval
becomes zero
STATEMENT B:
: In the case of a particle moving in a circular path with uniform speed the averag
speed is not equal to instantaneous speed
a) Both statements are true
b) Both statements are false
c) A is true, B is false
d) A is false. Bis true​

Answer 1

Answer:

c) A is true, B is false

Explanation:

in 1) at an instant speed is zero i.e particle is not moving so average speed is zero

2) if particle is moving with uniform speed then it should be equal to instantaneous speed

Answer 2

Answer:

both are false

If speed of particle is zero at an instant then Avg speed do the interval of time not Zero. And in case of particle moving in circular path with uniform speed the avg speed is equal to instantaneous speed
